OXI One MKII Workflows : Chords, Repetitions and Harmonization
video upload by OXI Instruments
"Welcome to Workflows – the series where we show you quick and powerful ways to create music fast.
In this episode, we’re diving into the chord sequencer and learn how to leverage its power with repetitions. Then we will use the harmonization feature on the previously made mono sequence.
Whether you’re sketching ideas or building a full track, this approach is all about speed, inspiration, and control. Let’s get into it."

"🔊 Scopri tutto sul Roland Jupiter-6, il sintetizzatore analogico a 6 voci del 1983 che ha lasciato un'impronta indelebile nella musica elettronica.
In questo video analizziamo la sua architettura sonora, la risonanza self-oscillante, il filtro multimodo, l’integrazione MIDI pionieristica, e il suo ruolo nel plasmare i lead Eurodance degli anni '90.
Utilizzato da artisti come Depeche Mode, Orbital, The Prodigy e fonte d'ispirazione per suoni alla Gigi D'Agostino, il Jupiter-6 è molto più di un fratello minore del Jupiter-8."

"We thought we'd make a video before shipping out this beautiful drum machine.
It's one of our very favourites: it holds lots under the hood, it's a joy to play around with and the variety of rhythms and poly-rhythms frankly seems kind of endless.
The 2 and 4 beat section, which is a matrix of independent patterns, is a a cool and unique add-on that Roland incorporated in a few of its very early drum machines.
The individual drum-sound volume-controls gives you just enough sound sculpting possibilities to not care that the machines is not programmable.
The drum sounds themselves are wonderful, woody and organic awhile at the same time analog and electronic."

"A favorite : Roland Rhythm 77 or TR 77 or the poor man’s CR78 but in our opinion the TR77 sounds better.
It also has individual volume controls for kick, hi-hats, snare and the guiro, an adjustable Fade out function - plus a separate, independent second rhythm section on a dial - as well as the possibility to play multiple rhythms at the same time.
Please check video of another unit we had available.
The Roland 77 has more features, sounds and rhythms than the similar-looking Acetone-branded drum machine.
This unit is in excellent condition, front panel looks almost new - but it has a small peel damage on the side panel visible in one of the photos.
220 V with Italian 3 prong connector - easily changeable to any connector"

"An American-made, analog drum machine with a distinctively woody tone and a remarkable feature no other drum machine posses - Modulation.
Swipe for a demonstration of how it operates [video previously posted here]
On the back is an audio input for modulating external instruments like guitar, organ or why not a string machine? Much like a side chain compressor, the external signal gets muted by the individual drum hits of the rhythm pattern engaged, almost like a tremolo but rhythmically syncopated.
There’s a slider to control the level of audible drums or instrument input signal.
10 drum sounds and 16 rhythm patterns are available to the user.
No individual volumes are at our disposal but a slider to emphasize the brighter or bass-y drum sounds.
Excellent condition unit with a small bump on the front wood panel.
110 Volt power with standard American power connector."
